We’ll make it simple, even if you’ve never looked under your hood before.

Brake fluid is the lifeblood of your vehicle’s braking system. When it’s low or contaminated, it affects how well your brakes respond—and that puts you and others at risk.

Pedal de freno suave o esponjoso
Brake warning light may turn on
Risk of total brake failure in extreme cases

Herramientas que necesitará (Hint: You Probably Already Have Them)

Paso a paso: How to Check Your Brake Fluid Level

Paso 1: Park on a Level Surface and Turn Off the Engine

Your vehicle should be on a flat, superficie estable. Ensure the engine is off and the hood is cool to the touch.

Paso 2: Pop the Hood and Locate the Brake Fluid Reservoir

Look near the back of the engine bay, toward the driver’s side.
The reservoir is usually a small, translucent plastic container with a black or gray cap labeled “Brake Fluid.”

? Consejo: Si no está seguro, consulte el manual del propietario.

Paso 3: Check the Fluid Level Without Opening the Cap

Most reservoirs are see-through and have “MIN” and “MAX” markings on the side. The fluid should be between these two lines.

If the fluid is below the MIN line, your braking power may already be compromised.

¿Cómo debería verse el líquido de frenos??

Condición de líquido de frenos	Apariencia	Lo que significa
Fresco	Claro a amarillo claro	Normal
Slightly dirty	Medium yellow/tan	Aging, but acceptable
Dirty or dark brown	Dark brown/black	Needs changing or flushing
Cloudy/milky	Cloudy or bubbly	Contaminated—may contain water

What to Do If the Fluid is Low

Si su nivel de líquido es bajo but there’s no leak, puede top it off yourself. Use only the recommended DOT-rated brake fluid (found in your manual or on the cap).

Sin embargo, if you notice any leaks or you’ve had to refill more than once, it’s time to visit a mechanic.

Brake Fluid Safety Tips

Never use the wrong type of brake fluid—it can damage your braking system.
Don’t open the reservoir unless necessary—brake fluid absorbs moisture from the air.
Wipe the reservoir cap before opening to avoid contamination.
Wear gloves if possible; brake fluid can irritate your skin and damage paint.

When to Check Your Brake Fluid

Errores comunes a evitar
